HI
Just received all the goodies I ordered Thanks !
I am having difficulty in deciding the location of the SDS011 sensor wrt the AQM11 pcb.
The SDS011 uses serial comms, however it is only +5 to 0V, not +- V as per standard.
Please can anyone tell me the maximum advisable distance between the ESP8266 and the SDS011, with reliable communication. Practical experience would be useful!
I would like to be able to choose a location for the sensor and AQMll and make off the correct length of cable with plugs and sockets and not have to do it twice!
many thanks
Patrick
